Campaign In Poland, 1939
"Poland, with the fifth largest army in Europe, was the first nation to feel the attack of the rejuvenated Nazi war machine. Because of later German conquests, the world has largely forgotten this initial success. Yet in one respect the rapid annihilation of the Polish Army was Germany's most important conquest. This campaign demonstrated to Germany, if not to the rest of the world, the correctness of her military doctrine. It furnished the proving ground for her organization and weapons. The rapidity of Poland's complete destruction came as a shocking surprise to the world at large. Eight days after the beginning of the war, all Polish forces were in demoralized retreat; and a month later, the entire fighting force of a million men had been annihilated. Military history offers no prior example of a conquest so rapid and complete. In this victory the new German air and mechanized forces played an unprecedented part. Nevertheless, it would be wrong to say that German success was due to these two arms alone. Simply stated, Germany's stupendous conquest may be attributed to the superiority of the entire German Army over the outmoded Polish war machine. Germany's balanced, well-trained, and ably led forces found no match in those of her smaller rival. This account of the campaign in Poland has been written for use in the instruction of cadets at the United States Military Academy. It is based for the most part on material prepared by the Military Intelligence Service, War Department."
